Kinetic Energy is the energy an object has while moving. An example is a ball rolling down a hill
Answer:
(a) Horizontal component of the launch velocity = 60.7m/s
(b) Vertical component of the launch velocity = 56.0m/s
Explanation:
Initial Kinetic Energy = (IKE)= 1670J, mass (m) = 0.49kg, hmax = 160m
IKE = 1/2mu^2
1670×2/0.48 = u^2
u^2 = 6816.3
u = √6816.3 = 82.6m/s
hmax = u^2sin^2A/2g
160×2×9.8/6816.3 = sin^2A
Sin^2A = 0.46
SinA = √0.46 = 0.6782
A = inverse (sin 0.6782)
A = 42.7° (angle of inclination to the horizontal)
(a) Horizontal component (Ux) = ucosA = 82.6×cos42.7° = 82.6×0.7349 = 60.7m/s
(b) Vertical component (Uy) = usinA = 82.6×sin42.7° = 82.6×0.6782 = 56.0m/s
Answer:
The correct option is;
B. Intensity
Explanation:
Communication style are an individuals observable pattern of behavior
Communication styles can be categorized into four groups which are
1. Emotive style: Sociability/dominance
2. Supportive style: low dominance/ High sociability
3. Reflective style: low sociability/low dominance and
4. Director style: Dominance/low sociability
Variations within each of the communication style is the intensity
Intensities includes;
Zone 1: low intensity
Zone 2: High intensity
Excess Zone: High intensity, high rigidity.
